nginx配置

server {
        listen 80;
        server_name chat.com;
        root /var/www/chat/chat/public;
    	index  index.html index.htm index.php;

        access_log /usr/local/var/log/nginx/chat.access.log main;
        error_log /usr/local/var/log/nginx/chat.error.log;

location / {
        if (!-e $request_filename){
            rewrite  ^(.*)$  /index.php?s=$1  last;   break;
        }
    }

    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

路由配置(没改动)

Route::domain(Env::get('route.url', ''),'api/robot');

请问这个是什么原因呢
